I Drying Fabrics, of which the following is a specification.

This invention consists of an improved arv rangement, construction, andcombination.of parts for securing the tentering, transit, and drying offabrics, illustrated by the annexed drawings, in which- Figure 1 is aside elevation of my machine, showing its general form. Fig. 1 shows indiagrammatic form a few of the supporting I rolls with thecarrying-chains, the operatinging the width of the inner frame to adaptit to different widths of fabrics. Fig. 2 is an end elevationof thesame, showing also the air-exhausting apparatus and the connectionbetween the same and the exhausting-pipes which extend across themachine. Fig. 3 is a side elevation of a section or portion of themachine, drawn on an enlarged scale in order to clearly illustrate theconstruction thereof. Fig. 1 is an end elevation of the same. Fig. 5 isa sectional elevation enlarged, about f 1111- size of tenter-hook chain,its slide, and a partition-piece. Fig. 6 is a plan illustrating twolinks of the said tentering-chain, the tentering-pins, and supportstherefor, and the slide- I piece. Fig. 7 represents one of theperforated telescopic rollers.

Similar figures refer to similar parts throughout the several views.

The parts 1 2 constitute the outer and inner frame-work of the machine,across which, at each end thereof,-are the telescopic or expandingrollers 3,- geared at their ends by spur-wheels 4 and the intermediateor carrier Wheels, 5, so as to rotate in proper direction, as shown moreparticularly in Fig. 1. The carrier-wheels 5 and the gears 4 receivemotion from the side shaft, 6, and worms 7 thereon, driven by a strap onthe speed-cone 8. The worm '7 meshes with a gear, 7, and on the axis ofthis is a pinion, 9", which in turn meshes With the gear 4 of theexpansible' roller 3, from which gear the carrier-wheels 5 transmit themovement. The several rollers 3 are connected by endless chains 9,linked and jointed, as shown at Figs. 5 and 6. The chains 9 (one foreach side) pass around the rollers 21 30, back and forth around therollers 3 3, and thence back again around rollers 21 30, through thecircuit of the machine, as shown in Figs. 1 and 1.

The holes 10 of the chains serve to gear the chains with lugs or pins 11on flanges 12 on the ends of each roller 3, whereby, as the rollersrevolve, the said chains 9 are caused to travel, after the manner of anendless belt. The chains are-supported between the several rollers3 byprojecting, slide-pieces 13, each having the recess 14 and theangle-iron 15, while the arm 16, extending from each link of the chain,is provided with hackle-pins or tentering-pins 17 and is supported bythe extended limb 18 of the slide 13, the hacklepins 1.7 being securedin short lengths of metal bars 19, so as to admit of the said barspassing round the flanges on the rollers On the piece or fabric 20 to betentered be formed a series of compartments or spaces,

22 23, between the several folds of the fabric, the spaces 22 beingopen-sided and having therein steam-pipes 24, while the spaces 23 areclosed at their sides by panels 25, and contain air-exhausting pipes 26,extending across the machine. Each of the pipes 26 has an aperture, 26,and is connected to the main vertical pipe 27, at the mouth of which isthe exhaustrfan 28, Fig. 2 also, the pipes 26 are closed or sealed attheir extremities, and can take in supply of air only through theopenings 26 therein.

The cloth to be tentered or dried is fed over the roller 21 and placedupon the hackle-pins 17 of the chains 9, whereupon the machine too willbe set in motion and the traveling chains 9 and revolving rollers 3 willdraw in the piece.

The parts of the inner frame, 2, which support the endless chains 9 aremounted on rollers, as shown in Fig. 4, and these parts are adjustabletoward or from each other to allow for different widths of fabric. Rodsor shafts pass through from one part to the other of the frame, beingprovided with right and left hand screw-threads, 31 32, and these rodsare in connection with a source of power by which they may be rotated toadjust the space between the parts of the frame, the mechanism for whichwill be hereinafter described. Each of the rollers 3 is, for a likepurpose, made so as to admit of endwise expansion and contraction bymeans of the perforated tubes 33, within which is the length of tube 34.The perforations in the tubes admit the-passage of air through theportion of the fabric thereon. The screws 31 32, for widening ornarrowing the inner frame, are rotated by means of the shafts B, onwhich are worms 0, gearing with and driving worm-wheels D on the ends ofthe screws 31 32. The shafts B are rotated by means of the handle 32,secured toone of the shafts, the movement of which is transmitted to theother shafts by the shaft 32 and pinions 32, Fig. 4c.

The cloth to be tentered and dried is guided by the attendant over theroller 21 to and upon the hackle-pins 17 011 the endless chains 9, assuch pins 17 in succession pass the roller 21, and the fabric is thusdrawn into the machine and over the several rollers 3 to the guideroller30, thence to the cuttle 36, and there is folded at 37. The cuttle isoperated in any well-known manner. In Fig. 1 I have shown thegeneralarrangement and mode of operating said device, which may bebriefly described as follows: The shaft or rollerA of the cuttle isdriven by means of a belt, B, from the shaft of the lowest of theexpanding and contractin g rollers 3. The roller A drives through abelt, B, a shaft, E, to a crank, E, on the end of which a rod, F, isattached, which is secured to the arm I of the cuttle and which eration,and as the air is drawn in at the open sides and circulates through oramong the steam-pipes it is precluded reaching the intake-openings 26,except by passing through the fabric 20, as it will be observed (seeFig. 5) that the part 18 of the slide 13 extends under the hackle-pins17, and in the next layer over the hackle-pins and fabric 20, as shownin Fig. 4, thereby effectually preventing circulation of air down thesides of the machine or otherwise than through the fabric when on itsway to the aperture 26" and exhaust-pipes 26 27.

I am aware that the use of steam-pipes, guide-rollers, arranged asdescribed, and exhaust fans and pipes are not new; nor the use ofendless chains having hackle or tenter pins; neither is the method ofcuttling or folding the piece new, and to these, therefore, I lay noclaim; but

What I do claim as my invention, and desire to secure by Letters Patent,is

1. The combination, in a machine for tentering and drying fabrics, ofside frames, a main exhaust-pipe having a series of branch pipes, 26,closed at their outer ends and having elongated slits or air entranceways, 26, steam-pipes 24, and the endless chain 9,having hackle-pins 17,with projecting partition slidepiece 18, all for the purpose andsubstantially as set forth.

2. In machines fortentering and drying fabrics, the outer frame, theinner adjustable frames, 2, the expansible rollers 3, the chains 9,supporting-slides 13, having projecting partition-pieces 18, and hackleor centering pins 17, for the purpose and substantially as set forthherein.
